 24 hour  -  -  -
 48 hour  6.173 mg/L  80000  493840 mg/L
 72 hour  6.233 mg/L  80000  498640 mg/L

Considering the water solubility for 48 hrs and 72 hrs the mean water solubility was calculated as follows:

Mean water solubility value for 48 hour run sample + 72 hour run sample

=(493840+498640 )/2

=496240 mg/L

Conclusions:
The water solubilitydetermination of test item Sodium naphthalene-1-sulphonate;CAS No.130-14-3 was done by spectrophotometric method. The water solubility was observed to be 496240 mg/L at 25°C.
Executive summary:

The water solubility determination of test item Sodium naphthalene-1-sulphonate (CAS No. 130-14-3) was done as per the OECD guideline 105 byspectrophotometric analytical method as per OECD 101. The solubility of (Sodium naphthalene-1 - sulphonate of 130-14-3 ) in water was observed to be 496240 mg/L at 25°C.

From above water solubility value, it is concluded that Sodium naphthalene-1 -sulphonate very soluble in water.
